Application that crashed: kontact
Version of the application: 4.3.1
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.30.5-yipeee i686

What I was doing when the application crashed:
I've opened KNotes inside the Kontact and found out that i have far too many duplicated notes. Actually, they weren't just duplicated, but ultiplicated. As it turned out there were only two different notes.
I selected one and pressed [delete]. The popup dialog asked if i wanted to delete the note. I decided that deleting might be too tedious with this dialog and so selected most of those notes. Pressed [delete] key and another dialog popped up. When i accepted that i wanted to delete notes the Kontact crashed with SegFault.
